SPECIFICATION forming part of Letters Patent No. 381,590, dated April 24, 1888.

Application filed January 3, 1888. Serial No.259,713. (N0 model.) v

To (L-ZZ whom it may concern.-

Be it known that I, h/IARION SLUTZ, a citizen of the United States, and a resident of Oanton, county of Stark, State of Ohio, have invented a new and useful Improvement in Tricycles, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to improvements in tricycles; and it consists in providing means for adjusting the frame and for securing the several parts in adjustment, as hereinafter de scribed.

My invention further relates to the manner of securing the seat-spring and the handlebar to the frame, also to the construction oidctail and combination of parts, as hereinafter set forth, and described in theclaims.

Figure l is an isometrical view of a tricycle, illustrating my invention. Fig. 2 is an elevation of front frame, and Fig. 8 a crosssection of back frame or hounds.

Similar letters of reference indicate corresponding parts in all of the figures of the drawings. A represents the front frame having at its upper end a threaded extension, (1, and projecting shoulders b, and at its middle portion an aperture, 0. At the upper end of said aperture is provided a downwardly-projected pivot, (l, and at the bottom end a pointed or conical ended set-screw, f. These pivotal points are adapted to conical sockets d and f on the under and upper side of the front por tion of the back frame, B.

The lower portion of the frame A is bifnrcated, the prongs C- being oval on the inside and flat on the outside, and provided at the lower end with an oval loop, 9. Overlapping slides D, fiat on their inside and oval on their outside and having journal-boxes k on their lower ends, are provided, as shown. The said slides are passed up through the loops 9, the flat part of the slide D resting on the flat part of the prong C and held in adjustment by the yoke F, the hows it, clasping the prong O and slide D, are secured by the bolts m. The axle n of the wheel G is supported by and rotated in the journalboxes h. On the end of said axle is secured a crank, H, and pedals J.

The rear portion of the back frame, B, is in the form of a V or angle bar, as shown in cross section, (see Fig. 3,) and passes through loops p on the forwardportion of hounds-frame K. A bridge, q, connects the lower edges of the frame between the loops 1), as shown in Fig. 3. Said bridge is provided with a threaded perforation, into which the thumb or set screw vZ is turned, and by which the parts are secured in desired adjustment. On the rear portion of the frame K is provided perforations 1, in which the axle s is secured.

To secure the seat-spring L to the back frame, 13, loops t and hooks '20 are provided, as shown, and integral therewith, the end of the spring, having perforations c, is passed through the loop 1., the books it through the perforation, and when the spring is released the energy being exerted outwardly will draw the end under the hook, by which it is so cured. The back frame, B, is secured to the frame A by the pivots d and f, as shown in The handle-bar M is provided with a groove, w, and perforation m, that fit onto the pin a and the shoulders b. The shoulders resting in the groove prevent the handle turning on the pin a, the not 7) securing the handle to the shoulders.

The object of my invention is to provide a tricycle that may be enlarged or contracted as required to adapt it tothe rider.

To enlarge the machine it is only necessary to slack the bolts m in the hows it of the yoke F, and to push the yoke down to the desired point, at which it may be secured by turning the bolts in again; and to further enlarge it the screw Z may be slacked and the frame K moved down on the back frame and secured in desired adjustment, and to reduce the size slide the adjustable parts together.

In order to produce a light yet strong and I durable machine and to rcduceinitial cost the\ frame is preferably made of malleable cast iron.

oated front frame, the prongs of which are made 1 co in sections, one of said sections provided with a journal-box for the axle-shaft, the other with a securing-loop,vand the yoke F, having the clasping-bows 7c, and the set-screw m,by which the parts may be secured in adjustment, substantially as described, and for the purpose 5 set forth.

2. The combination, in a tricycle, ofa back frame formed of two sections, B and K, the rear portion of section B of a V or angle form and the front portion of section K having a rc corresponding socket-,and the screw Z, by which the two frames may be secured in desired adjustment, substantially as described, and for the purpose set forth.

3. In a tricycle, the combination of the back I 5 B, spring L, loops t, and the hooks u, substan-
